To all whom it may concern:

Be it known that 1, WILLIAM H. RAMM, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Submarine-Boat Attachments, of which the following is a specification.

My invention relates to new and useful improvements in a submarine boat attachment and more particularly to an indicator for locating the position of a sunken sub-v marine boat.

The primary object of the invention is the provision of such an attachment which will not retard the operation of the boat and which may be easily released at the desired moment.

A further object of the invention is the provision of means for severing the connecting means whereby the attachment is re leased from the boat.

A still further object is the provisionof means for connecting the cable to the submarine boat after the indicator has been released.

lVith these and other objects in view the invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following description and drawings, in which:

Figure 1 is a perspective view showing the sunken boat with the indicatorsreleased and upon the surface of the water. Fig. 2 is a transverse vertical section through the boat and indicator attached thereto. Fig. 3 is a longitudinal vertical section on the line 33 of Fig. '2. Figri is a detail in plan of the supporting drum. Fig. 5 is a longitudinal sectional detail of the cable drum and casing therefor. Fig. 6 is a fragmental detail of the cable severing knives. Fig. 7 is a top plan of the indicator. Fig. 8 is a sectional view of the .top of the supporting drum housing. Fig. 9, is a vertical section through the cable-connecting. block. Fig. 10 is a transverse sectional'view through the cableconnecting block. Fig. 11 is a vertical sectional detail of one of the releasing slides for the cable-connecting block, and Fig. 12

is a side elevation showing in detail the cable connector.

In describing my invention 1 will separate the several details into three sections, namely, the fastening mechanism for holding the indicator floats to the submarine boat, the severing mechanism for releasing the indicators or floats from the boat, and the cable-connecting mechanism for connecting the ends of the cable for supporting the boat from the indicators or floats.

In Fig. l of the drawings I have shown a perspective view of a sunken submarine boat supported from the indicator floats'and have indicated the submarine boat generally by A and the indicator floats by B.

Fastening mechanism.i Vithin the submarine boat A are provided two casings l which are supported upon the brackets 2 and within these casings 1 are mounted the rotatable drums 3 upon which, are wound the cables 4. Secured upon the top of the submarine boat is a casting 5 having the groove 6 formed in the top thereof, as more clearly shown in Fig. 8 of the drawings, and within the groove is adapted to'be re-- ceived a rubber packing. A drum 7 is mounted within the casting and the purpose and operation thereof will be later de scribed. Surrounding the casting 5 is a casing 8 and the indicating float B is adapted to rest upon the casting and is provided on the bottom with the tongue 9 which is adapted to be received within the groove 6 and upon the rubber packing. Connected to the casings l are the pipes 10 which eX- tend from the casings to the top of the boat and are connected to a plate, as indicated at 11. The cables 4 are adapted to pass through the pipes 10 and through the top of the boat and are connected to an eye 12 which is secured to the underside of the indicator float B. Tubes 13 extend vertically through the indicator float, as more clearly shown in Fig. 3 of the drawings, and passing through these tubes 13 are the rods 14 having the ends threaded to receive the nuts 15 and between the nuts and the top of the float are the washers 16 which prevent water from entering the tubes 13. Extending from the top of the casing 8 and into the,

top of the submarine boat are the pipes 17 which are in alinement with the tubes 13 and connecting the ends of the pipes 17 on the interior of the boat are the pipes 18 and casting 19. The rods 14E are provided on the lower ends with eyes and connected to the eyes and passing through the pipes 17, the connecting pipes 18 and casting 19 is a cable 20. This cable 20 acts as the connecting means for holding the indicator float to the submarine boat. It will be understood that when this cable 20 is severedthe indicator float will rise, drawing the cables &

through the pipes 10 and from the drums 3.

Scoem'ng mechanism-The severing mechanism is more clearly shown in'Figs. 2, 3 and 5 or" the drawings, and comprises a cylinder 21 connected to the casting 19 having a pipe 22 entering the bottom thereof and said pipe 22 is connected to any source of compressed air supply. A; piston 23 operates within the cylinder and is provided with the upwardly extending rod 24 which has the sharpened end 25 and a. coil spring 26 surrounds the rod between the piston head and the bottom of the casting. The casting is provided with a central opening through which the rod 2 1 passes and is also provided with a shoulder upon which is secured a blade 27 which acts with the pointed end of the rod 24 for severing the cable 20. It will be understood that when it is desired to sever the cable to release the indicator float air is admitted to the bottom of the cylinder which forces the piston upwardly and thereby sever's'the cable between the pointed end of the rod 25 and the blade 27.

Gable-connecting mechanism-On the endsot the cables 4 which are connected to the indicator floats B and wound upon the drums 3' are secured the balls or enlargements 28, as more clearly shown in Fig. 9 of the drawings. indicator float is "released from the boat and the boat sinks to have some means for connecting the two free ends of the cables 1, whereby they will support the boat and connect the float thereto. For this purpose I have provided the blocks 29 which are supported upon the top of the boat and are provided with central openings 30' which are adapted to register with the openings of the pipes 10 which extend through the top of the boat. These blocks 29 are supported upon the top of the boat by means of sliding bolts 81 which pass through angle iron brackets 32 secured to the boat and enter depressions or sockets 33 formed in the blocks 29', as more particularly shown in Fig. 10 of the drawings. Sockets 3 1 are formed in the blocks 29 adjacent the central opening 30 and within the sockets are received the sliding blocks 35 having the extensions or stems 36 which It is necessary when the the blocks 35. Theblocks 29 are provided with sockets 40 to receive the enlarged heads 4:1 otpins' 42 which. pass through open ngs 1n the blocks and are adapted to engage 1n openings in the sliding blocks and rest upon the top otthe pins 38. Plugs ib are received in theends of the openings a0 and between the enlarged heads -11 and plugs 13 are held springs 4.4.. Lugs 15 are formed on the blocks 29 and connected to the lugs 45 of the two adjacent blocks is a cable 46.

When the indicator float isreleased and the cable drawn from the drum the enlarged heads 28- on the ends of the cables will be drawn through the pipes 10 until they engage the pins 38 carried by the sliding blocks The lugs 19 will force the pins 39 backward until the lugs are above them, when the pins will return to their normal position thereby holding the pins 38 in a raised position. The pins thus raised will release the pins 42 from the sliding blocks and the blocks will then be forced back into the sockets 34 and the stems on the sliding blocks will disengage the sliding bolts 31 from the sockets formed in the blocks 29. The blocks thus being released from the boat will be allowed to rise and the cable 16 will engage and surround the underside of the drums '7. It will thus be seen that the ends of the cables are connected and by engaging the underside of the drum will support the boat.

The indicator float may be made of any desired shape but preferably that shown in Figs. 3 and T of the drawings, and is provided with a plurality of windows +17 'and the removable plate 48 by means of which a person may enter the float. The indicator float may carry a signal light, a sounding signal and telephone and wireless telegraphy connections.

Having fully described the detailed construction of the device it is thought that the operation and advantages will be clearly understood.

lVhile in describing the invention I have merely described the construction and operation of one indicator float and connecting andsevering mechanism it will be understood that two or more of these indicator floats are carried by each boat. Preferably there will be two floats, one fore and one aft of theboat. Should the boat sink or become. disabled in any manner so that it is not able to rise to the surface of the Water it is only necessary for the operator to admit air into the cylinder 21 which operates the piston and severs the cable, thereby disconnecting the float from the boat. The float Willthen rise to the'surface unwinding the cables from the drums until the enlarged heads on the cables disengage theblocks which carry the. connecting cable. The connecting cable engaging the drum 7 Will support the boat from the floats which are of suflicient, buoyancy. to support the boat. #In order that the cables cannot be twisted by the floats turning, I have provided means for connecting the floats, said means, as shown in Fig. 1 of the drawings, merely consisting of a cable connected to the ends of the floats. However, I do not Wish to limit myself to this particular form of connecting means as any means might be used. The floats may be either released from the boat While the boat is sinking or may not be released until the boat has settled to its greatest depth. If the floats are not released until the boat is settled they Would have to be of suflicient buoyancy to-ivitl1- stand the pressure of the Water at such a depth and rise to the surface.

The floats beingron the surface of the Water Will indicate to other boats that the boat is sunken and allow them to raise the same. In raising a boat of this character it will ordinarily be found that the cables connected around the drums will not be of suflL cient strength to raise the boat but this can be easily overcome by merely securing any heavier cable to one end of the supporting cable and by drawing'the opposite end the larger or heavier cable is drawnaround the supporting drum and may then be attached to any form of hoisting mechanism for raising the boat. f
